How to set up Zwift on a smart trainer with ERG mode

[TourDeTony]

The emphasis on user setup is spot on. It raises a critical question: how do minor adjustments—like saddle height or cleat positioning—impact resistance accuracy in ERG mode? Could the cumulative effect of these tweaks create a significant difference in performance?

Also, considering the varying environmental factors, such as room temperature or humidity, how might these influence the smart trainer's responsiveness? Are there specific conditions that exacerbate the inconsistencies in resistance control? Exploring these aspects could shed light on the broader challenges users face with ERG mode. What insights do others have on this?

I see where you're coming from, but focusing solely on equipment tweaks might lead us to overlook the impact of rider's exertion levels. Even small fluctuations in effort can affect ERG mode's performance. And yes, environmental factors play a role too, but let's not forget that our own bodies can be just as unpredictable. Could our physiological responses to exertion be a significant variable here?

Rider exertion levels can certainly throw a wrench into ERG mode's reliability. But let's not ignore how inconsistent the calibration process is across different trainers. Could it be that many users are following outdated or vague calibration instructions, leading to skewed resistance feedback?

Further, what about the rider's muscle fatigue throughout a session? If fatigue is affecting performance, how is that impacting the trainer’s ability to maintain desired wattage?

And if we dig deeper, could the interplay between rider input and the trainer's software be the real culprit behind these discrepancies? Maybe the communication lag isn't just about equipment; perhaps it’s also about how the rider engages with the workout.

So, how do we ensure that our setups are not just technically sound but also responsive to these human factors? What’s the relationship between proper calibration and the rider's physiological responses during a workout?
